Results and discussion

Any other information on results incl. tables

The reaction enthalpy (DHREAK) was calculated from the standard formation enthalpies (DHFORM) of the substances involved. The data comes from the NBS tables. In the two comparative reactions I assumed the value for ionized HCl in aqueous solution for DHFORM for HCL. The reaction enthalpy of the AlCl3 reaction is the highest, so one can definitely speak of “reacting violently with water”. The specified temperature increases are incorrect (too high): The increase in Cp’s with increasing temperature is not taken into account and the Cp of the HCl that is produced is uncertain (dissociation, concentration dependency). As a relative comparison, the values ​​are a first indication. TiCl4 and CH3COCl are legal classified with EUH014.
